Abstract

Abstract: The metal organic framework material Cu3 (btc)2 ·3H2 O (HKUST‐1) was grown on differently activated oxide‐bonded SiC ceramic foams with varying pore sizes. Activation was performed by an alkaline etching procedure under dissolution of the SiO2 binder phase in the ob‐SiC microstructure leading to an increase in strut surface roughness. The influence of foam pore size, etching conditions (duration, temperature) and the effect of a subsequent alumina coating to increase the coverage with –OH moieties was studied. The activated foams and MOF@ob‐SiC composites were characterized by microstructural analysis, H2 O adsorption and thermal conductivity measurements. Abstract : A method for the crystallization of the metal organic framework HKUST‐1 on activated open‐celled SiC ceramic foams is presented. The resulting micro‐macroporous MOF@SiC composites were characterized by SEM, powder X‐ray diffraction, confocal Raman spectroscopy, H2 O adsorption and thermal conductivity measurements.
